8 Claims.

This invention relates to improvements in looking mechanism formanipulative devices in accounting machines.

This application is a divisional application of application Serial No.116,004,,filed by Warren P. Loudon on September 16, 1949, now Patent No.2,628,774.

The invention is shown applied to a machine of the type disclosed inUnited States Patents No. 2,209,763, issued to Ernst Breitling on July30, 1940, and No. 2,587,019, issued to Frank R. Werner on February 26,1952; and in the copending applications for United States Letters Patentof Frank R. Werner, Serial No. 46,165, filed August 25, 1948, and SerialNo. 58,114, filed November 3, 1948.

The principal object of the invention is to provide a machine of thetype disclosed in the above-mentioned patents and applications for useby cooperative societies, and, as illustrated herein, the machine isadapted for use in Great Britain, where cooperative societies are wellorganized and consist of many cooperating stores.

The object of theinvention is to provide an interlock to prevent theadjustment of amountsetting manipulative devices when a specialmanipulative device is moved into a certain position.

With this and incidental objects in view, the invention includes certainnovel features of construction and combinations of parts, a preferredform or embodiment of which is hereinafter described with reference tothe drawing which accompanies and forms a part of this specification.

.Of said drawing:

Fig. 1 is a side view of an amount manipulative device.

Fig. 2 is a side view of a special transaction lever. and an interlockactuated thereby.

Fig. 3 is a detail front elevational view showing the side spacing ofthe amount and transaction manipulative devices, together with theinterlock actuated thereby.

General description As disclosed in the parent application, theright-hand half of the machine embodying the invention comprises a setof amount setting levers, a transaction lever, and a clerks lever,together with four machine release keys. In certain business systems,particularly in cooperative stores, as operated in Great Britain, inwhich members of a cooperative association are entitled to receiverebates, a record is kept of their particularaccounts. If a. customerwho is a non-member of the association makes a purchase, it is thendesirable to print a code on the perforated strip (illustrated in theparent case) indicating such, so that the data will not be added into anaccount. In order to control such auditing, a special code is perforatedon the perforated strip before the entry of the sale to a non-member isentered into the machine. Setting of the transaction lever to its ninthposition controls certain interlocks in the machine, which prevent theadjustment of the amount levers and also prevents operation of a receiptprinting and issuing mechanism. Thereafter, upon operation of themachine with the amount levers all set at zero, a code is perforated onthe perforated strip adjacent the non-members account number, whichaccount number may represent an account number of another association,and therefore, when the perforated strip is later analyzed, the specialcode perforated on the strip controls the analyzing machine to skip theentry of the amount which is entered on the perforated strip immediatelyfollowing the operation in which the code is printed. After the code isprinted, the amount of the purchase is set up on the amount levers andthe normal operation of the machine is made, whereupon the data isperforated on the strip.

Amount setting manipulative devices Loose on the main shaft 37 (Figs. 1and 3) is as amount lever 10 for each denominational order, an upwardextension of which terminates in a finger piece H, which protrudesthrough a corresponding arcuate opening in the cabinet of the machine.Each of the levers 10 has a plurality of v-shaped notches 12 cut in asegmental portion thereof. Said notches correspond to the differentpositions of the levers and are adapted to cooperate with respectiverollers it, each of which is mounted upon a corresponding lever 14,loose on a shaft 15 supported by the frames 29 and 30 (Fig. 3). A springit, connected to each lever 14, urges the levers 14 clockwise tomaintain the rollers 13 in engagement with the notches 12, therebyproviding a means for locating and retaining the amount levers 10 in setpositions. Each of the setting levers is connected by a link ll to acorresponding mechanism for setting an indicator, and each lever isprovided with teeth 35 for setting type carriers, and also a stud foractuating a totalizer differential segment in the manner disclosed inthe above-mentioned patent to Breitling and in the parent case.

Each of the settable levers it has a segmental portion of gear teeth 85,which mesh with a corresponding drive gear to set a corresponding typewheel.

Transaction setting manipulative devices Adjacent the highest orderamount lever 1d, a lever 290 (Fig. 2) is provided for controllingcertain functions in the machine, as disclosed in the parent case. Whenthis lever is moved into its ninth position, means are adjusted to lockthe amount levers against movement. The lever 280 is provided with teethfor setting type carriers; a link 298, for setting an indicator; and alink Etl, for actuating a control element, all as fully described in theparent case.

Interlock between transaction and amount manipulative devices In thesystem in which the present invention is illustrated, it is necessary toprevent the recording of amounts on the perforated strip when thetransaction lever 2E0 (Fig. 2) is in the lowermost, or nine, position.such aresult, a means actuated by the transaction lever positions a lockin the path of the lever 14 in each amount bank to lock the res'p'ectivestuds 13 in the notches T2 of the amount lever.

To accomplish this result, the transaction lever 200 is provided with astud 839, which is moved into the chain-line position when the lever isset into it's eighth position. In this po- 'sition, the stud 830contacts a lever BSE, and, upon "movement of the lever 2M! into itsninth position, the stud 830 lifts the arm 83% to move around the shaft31, upon which it is pivoted. The arm 83! is connected to an arm 832 bya link 833. The arm 832 is connected to a sec ond arm 832 by a yoke 834,and the arms 8-32 are pivoted 'on a shaft 2 [8. A spring maintains thearm 832 in lowered position, with a toe 836 o'n'the 'arr'n 832 against ashaft 365. The arms 832 carry a rod 838, which extends across the planesof all the levers 14 of the six amount bank's. When the lever 200 ismoved into its ninth position, the rod 833 is lifted into the paths ofthe lower ends of the levers M, thus locking the studs 13 in the notchesof the amount levers, to prevent any movement thereof.

While the form of mechanism shown and described herein is admirablyadapted to fulfill the object primarily stated, it is to be understoodthat it is not intended to confine the invention to the form orembodiment disclosed herein, for it is susceptible of embodiment invarious other forms.
